I feel very little about being an INTJ. If I weren’t an INTJ, I’d be something else, and that’s fine too. It’s not a huge deal.
It’s like your blood type- on a few very specific occasions it’s really helpful to know your type, and it’s something you might want to tuck away in your memory forever, and it might be something you are interested in, but in general, it’s largely useless information. Knowing your type probably shouldn’t and wouldn’t largely alter your life, but might offer some clarity and insight where there was none before. That is the purpose it serves.
Also, if somebody in meatspace seems overly interested in your type (either sort), you may want to consider running the other way very quickly.
